ROTARY DEHUMIDIFIER AND METHOD FOR DEHUMIDIFICATION

摘要

PURPOSE: A rotary dehumidifier and a method for dehumidification are provided to reduce power needed for dehumidification and regeneration, and to efficiently dehumidify. CONSTITUTION: A dehumidifier includes a casing having a dehumidifying area(16) and a regenerating area(14) formed therein in circumferential direction; a rotor(18) impregnated or coated with dehumidifying agent, and installed to rotate in the dehumidifying area and the regenerating area in the casing; a regenerating air supply unit(12) connected with the casing, and supplying air into the regenerating area for regeneration of the dehumidifying agent; a processing fluid supply unit(13) connected with the casing to supply processing fluid into the dehumidifying area for dehumidification process; and a regenerating unit installed in the regenerating area to directly heat only a part of the rotor in the regenerating area so as to regenerate the dehumidifying agent passing the regenerating area with regenerating air passing the regenerating area.
